Argentina ended Wales' World Cup journey in controversial fashion during an enthralling quarter-final in Marseille.

Tomos Williams restored Wales' lead with a brilliant effort before two late tries from Joel Sclavi and Nicolas Sanchez sealed the win.

The Pumas face Ireland or New Zealand in the semi-final in Paris next Friday.

The match swung on a controversial decision by English referee Karl Dickson who had replaced Jaco Peyper early on in the game after the South African official suffered a calf injury.

Wales were leading 17-12 when Argentina lock Guido Petti's shoulder caught the head of Wales centre Nick Tompkins at a ruck.

Dickson decided Petti's action was legal and gave no sanction and Pumas prop Scalvi went on to score to give Argentina a 19-17 lead.

With Wales chasing the game, Sanchez intercepted a Sam Costelow pass to sprint away to score and added a late penalty to rub salt in the wounds and send Warren Gatland's side home.
